Negative Charge Pump Design Considerations
The criteria for the negative charge pump is similar to the
positive charge pump. For a single stage charge pump, the
maximum V OFF output voltage is:

S CPN S OUT2
Similar to positive charge pump, if additional stage is
required, the LX switching signal is recommended to drive
the additional charge pump diodes. The figure on the next
page shows a two stage negative charge pump circuit.
